TUMBLING-BARREI.

Specification of Letters Patent.

Application tiled Kay 28, 1913. Serial No. 770,444.

Y To all whom t may concern:

Be it known that I, FREDERICK E. WAiiNER, a cltizen of the United States, residing at Bridgeport, in the county of Fairfield and -State of Connecticut, have invented certain new and useful Improvements in Tumbling- Barrels, of which the-following is a specification. ,3

My present invention pertains to improvements in tumbling barrels, and more specifif cally to an'improvedmean's for heating the same. l

The invention in its preferred form is` illustrated in) the annexed drawings, wherein:

Figure 1 is a sectional .elevation of the barrel and its mountin Fig. 2 a sectional view of the barrel-hea taken on the line 2-2 of Fig. 1, illustrating the interior construction of the barrel-head; Fig. 3 a transverse sectional view, on an enlarged scale, on the line 3-3 of Fig. 1; Fig. 4 a longitudinal sectional view on the llne 4-4 of Fig. 1, taken at right angles to the section of said figure, andthe barrel being rotated a.

q narter turn;l Fig. 5 a sectional yview on the line ,5-5 of'- Fig. 1, also illustrative of the constructionof the barrel-head; and Fig. 6

a side elevation ofthe steam pipe connections, illustrating their relation to the dumpi or swinging axis of the barrel.

` he main object ofthe present invention is to provide a superior means forv heating the barrel; to so construct such means that it will clear itself of condensed steam; and also to provide steam-connections which will allow the barrel to be tilted as may' be desired, v,while the steam is still on, and lis without the use of rubber hose or the The barrel and its support, andthe rotay tive and tilting means therefor are for the` pur ose of illustration substantially the same as t ose shown and set forth in Letters Patent No. 978,524, granted to meunder date of December 13, 1910, though as vwill be apparent the invention ma be applied to almost any form of barre In the drawings, 1 denotes the fixed base or standard in which is swiveled, upon suitable bearings or hubs,a frame 2, which latter forms the support for the barrelsustaining and rotating shaft 3. shaft has secured to it a worm gear 4, towhich 1110-' tion is imparted through a worm gear (not shown) carried upon a driving-shaft 5, which is concentric with the swivel bearing of the frame 2. Fast and loose pulleys 6 and 7 are mounted on shaft 5.

A sector-shaped rack 8 is carried by frame 2, and through pinion 9, gear 10, .pinion 11 meshing with sald ear, and crank 12 secured to the shaft whic carries pinion 11, the frame 2 and the parts su ported thereby may be rocked or tllted as esired. All'this mechanism is common to the patent aforesaid, to which reference is made for a more detailed description.

The barrel-body may be said to comprise an inner shell or lining 13, an exterior shell or wall `14, an outer connecting and spacing ring 15, and a head 16, the lining 13 bein secured to an upstanding collar 17 forme thereon.

The head is.provided with a relatively large hub 18, to which shaft is keyed. Said head is hollow, forming a chamber 19, into which live steam passes, .through a port 20, formed in hub 18, the head likewise having a discharge channel 21, communicating at `its inner end with a discharge port 22, also formed in the hub. A pipe coil 23 is placed between the shells 13 and 14 of the .barrel and preferably in close contact with the inner wall or shell, the inner end of the coil being incommunication with chamber-19, while the outer end is connected by a pipe 24.-'with the exhaust channel 21. Asbestos or other suitable heat-insulating material 25 will be packed between the coil and the ex.-

`terior shell 14 of th'e barrel.

Loosely mounted on shaft 3 and bearing closely against a packing washer 26 vinterposed between it and hub 18, is a collar 27, said collar being provided with two concentric grooves 28 and 29 in the face thereof. Groove 28 is in constantA communica-tion with port 20 and with a steam supply pipe 30, threaded in an o ening formed in the collar `which communicates with channel or groove 28, while groove 29 is in constant communication with an exhaust pipe '31. Saidvpipes 30 and 31 are extended to one or the othery side of the frame 2 of the 'apparatus and are connected to the supply and exhaust mains 32 and 33, Fig. 6, by swivel joints 34 and 35', which joints are located 1n line with the axis about which the frame 2 .is tilted. By preference spring-pressed pins 36 and 37 will be interposed between the -frame 2 and the-.collar 27, said pinsiur'g'.`

washer will, of course, be providedwith suitable openings registering with the channels 28 and 29 andthe ports 20 and 22. The operation of theapparatus is as follows: When it is desired to heat the barre/L steam is admitted into the main'32, passing thence through pipe 30 and into the vchannel 28. From said channel it passes through the port 20 into. the main chamber 19 formed in the head of the barrel, thence into coil 23, entering the lower end thereof, as indicated by the arrows in Fig. 1, and passing through the various convolutions thereof toward the outer or discharge-endof `the barrel. It then passes through the pipe 24, into the discharge channel 21, through port 22 in the channel 29, thence through exhaust pipe 31 into the exhaust mam 33. The action of the steam will drive any water of condensation before it and a constant cir- 'culation will befthus maintained throughout the coil and through the head of the barrel. rlhe rotation of the barrel also-'serves to carry the zwater of condensation forwardly and if for any reason the coil should become clogged by the water Ion account, for instance, of lack of proper steam pressure,

it may be readily cleared bymerely tilting' the barrel.

It will be further noted that the swivel connections between' the pipes 30 and 31 and the mains 32 and 3.3 are in axial alinement with the shaft or bearings upon which the barrel is tilted, so that there is no necessity for the employment of lrubber pipes, slip joints or the like, and consequently 4there is little or lno wear upon the'parts.

Again,` there is no necessity for shutting I 0E the 'steam while the barrel is being tilted and the rotation'of the barrel does not a'ect 'the1 passage of the steam into and from thev cui While the steam connections and 'parts have-been describedlsomewha't in detail, it is' obvious that the structure may be modified without departing from the spirit of the invention, so long as the` functions herein set forth are retained.
